Adding Parent Record if None Exists in Microsoft Access

In this Microsoft Access tutorial I will show you how to automatically add a parent record if the user tries to add a child record in a subform first thus preventing an orphan. We will automatically add an order record if the user starts adding an order detail record and the order doesn't exist yet. We will then set up referential Integrity to prevent future orphan records if the user deletes the order.
